Methods and apparatus for performing knee arthroplasty

摘要

Methods and apparatus for performing knee arthroplasty, including, but not limited to, bicruciate retaining knee arthroplasty, are described herein. Methods and apparatus for preparing a distal femur for a femoral implant as well as methods and apparatus for preparing a proximal tibia for a tibial implant are described. These methods and apparatus, in at least some embodiments and uses, facilitate decreasing the complexity of knee arthroplasty procedures such as bicruciate retaining procedures, while maintaining, if not improving on, the safety, accuracy and/or effectiveness of such procedures.

主权项

1. A tibial plateau resection guide, comprising:
(a) a cutting block defining a horizontal guide for guiding a tibial plateau resection; and (b) an elongated flag pin for positioning the cutting block with respect to a proximal tibia, the elongated flag pin having an elongated portion extending along a longitudinal axis, the elongated flag pin including an enlarged head portion having a substantially planar surface; wherein the cutting block defines an opening for receiving at least a portion of the enlarged head portion such that the cutting block cannot rotate relative to the elongated flag pin about the longitudinal axis of the elongated flag pin when the enlarged head portion is positioned in the opening in the cutting block, wherein, while the substantially planar surface of the enlarged portion is positioned in the opening in the cutting block, the cutting block is permitted to rotate relative to the elongated flag pin along the substantially planar surface and the cutting block is slidable along the substantially planar surface, and wherein the horizontal guide has a guide surface defining a plane that intersects the opening in the cutting block.
